Which symptom is commonly associated with A-B lipoproteinemia?

A-B lipoproteinemia is a genetic disorder characterized by the inability to transport lipids in the bloodstream effectively, primarily due to a deficiency of apolipoprotein B. This condition results in the accumulation of lipids, causing various symptoms. Steatorrhea, which is the presence of excess fat in stool, is commonly associated with this condition. It occurs because the body cannot properly absorb dietary fats due to the lack of lipoproteins necessary for transporting these fats from the intestine into the bloodstream. Consequently, undigested fat gets expelled in the feces, leading to steatorrhea.

The other symptoms listed are linked to different metabolic or physiological conditions. Hypoglycemia relates to low blood sugar levels, hypercholesterolemia pertains to high cholesterol levels, and hemorrhage is associated with bleeding disorders. While some of these may occur in other lipid metabolism disorders, they are not characteristic of A-B lipoproteinemia, thereby making steatorrhea the most relevant symptom in this particular case.
